IRG4PC50W datasheet

• Designed expressly for Switch-Mode Power Supply and PFC (power factor correction)applications
• Industry-benchmark switching losses improve efficiency of all power supply topologies
• 50% reduction of Eoff parameter
• Low IGBT conduction losses
• Latest-generation IGBT design and construction offers tighter parameters distribution, exceptional reliability

• Lower switching losses allow more cost-effective operation than power MOSFETs up to 150 kHz(“hard switched” mode)
• Of particular benefit to single-ended converters and boost PFC topologies 150W and higher
• Low conduction losses and minimal minority-carrier recombination make these an excellent option for resonant mode switching as well (up to >300 kHz)
